Can I somehow get the file data in the archive (index, size, etc.) without going through all the files?

Like for example in DotNetZip:

ZipFile zip = new ZipFile("1.zip"); long size = zip["dir\\file.txt"].UncompressedSize;

    Are you sure that ZipFile doesn’t ZipFile them inside? It seems that SevenZipSharp does not support such indexing, but nothing prevents you from entrusting the First method to a brute force:

     using System.Linq; ... var extractor = new SevenZipExtractor("test.7z"); var size = extractor.ArchiveFileData.First(f => f.FileName == "dir\\file.txt").Size;

    If you wish, you can write an extension method:

     public static long GetFileSize(this SevenZipExtractor extractor, string fileName) { return (long)extractor.ArchiveFileData.First(f => f.FileName == fileName).Size; }
